The S&P/ASX 200 Index (ASX: XJO) kicked off August with a brief but fierce sell-off.
Aussie stocks came under pressure alongside European and Asian shares as the S&P 500 Index (SP: .INX) and Nasdaq Composite Index (NASDAQ: .IXIC) plunged amid concerns that the United States was heading for a recession.
While long-term investors largely held tight (wise move!), traders sent global markets roiling amid speculations that the US Federal Reserve has waited too long to begin cutting interest rates in its efforts to tamp down inflation.
The official Federal funds rate stands at a 20-year high of 5.25% to 5.50%, a level its been held at for more than a year now.
But as quickly as it devolved, investor sentiment took a rapid turn for the better as new data indicated the world's top economy was still humming along.
Indeed, since closing down a precipitous 3.7% on 5 August, the ASX 200 is up 4.3%.
In fact, with yesterday's positive finish, the benchmark index has closed in the green for nine out of the last 10 trading sessions.
But with markets obviously still on edge, could Federal Reserve chair Jerome Powell send global stock markets and the ASX 200 diving again?
Powell's Jackson Hole address
As you're likely aware, this week is the Fed's annual Monetary Policy Symposium. Each year, it takes place in the mountain town of Jackson Hole, located in the US state of Wyoming.
The event brings together central bankers and economists from around the globe.
Global and ASX 200 investors alike will be on the edge of their seats on Friday (Saturday night Aussie time) when Powell delivers his highly anticipated speech.
While few analysts expect Powell to offer any concrete statement on the Fed's next interest rate move, set to be reported on 18 September, the big question is whether he may signal the likelihood of a larger 0.50% cut.
What the experts say ASX 200 investors should expect
Commenting on the building hype surrounding Powell's Jackson Hole presentation, Josh Gilbert, market analyst at eToro, said, "Powell's remarks will probably be of extra interest, given that the central bank appears very close to lowering interest rates from their current two-decade high."
Gilbert believes that global and ASX 200 investors are likely to hear that US interest rates are coming down, but the market's reaction will be influenced by the expected size of those cuts.
According to Gilbert:
Employment rates are weaker than expected right now in the US and inflation continues to ease in the region, meaning analysts won't be looking to see if they're cutting, but an indicator of how much they're likely to cut by.
Eric Beiley, executive managing director of wealth management at Steward Partners Global Advisory, cautioned that a hawkish tone from Powell could see traders rushing for their sell buttons.
"If traders hear cuts are coming, stocks will react favourably. If we don't hear what we want, that would trigger a big selloff," he said (courtesy of Bloomberg).
"Markets are so confident that rate cuts are coming very soon. It would be a huge surprise if Powell didn't reinforce that's the path ahead," Beiley added.
Indeed, depending on the nuance of his speech, Powell could potentially send US stocks and the ASX 200 into a tailspin.
"His tone is crucial. If he shocks the market and is hawkish, stocks will react negatively," Stephanie Lang, chief investment officer at Homrich Berg said.
